West African Monetary Zone

Wikipedia short information

Formed in 2000, the West African Monetary Zone (WAMZ) is a group of six countries within ECOWAS that plan to introduce a common currency called the Eco.[23] The six member states of WAMZ are
Gambia, Ghana, Guinea, Nigeria and Sierra Leone who founded the organization together in 2000 and Liberia who joined on 16 February 2010. Apart from Guinea, which is Francophone, they are all
English-speaking countries. Along with Mauritania, Guinea opted out of the CFA franc currency shared by all other former French colonies in West and Central Africa.

The WAMZ attempts to establish a strong stable currency to rival the CFA franc, whose exchange rate is tied to that of the Euro and is guaranteed by the French Treasury. The eventual goal is for the
CFA franc and Eco to merge, giving all of West and Central Africa a single, stable currency. The launch of the new currency is being developed by the West African Monetary Institute based in Accra,
Ghana.
